Sorry for the newb move, but who better to ask than the enthusiasts?

I'm thinking about purchasing an '07 S6; this one to be specific - AutoTrader Link

I drove it yesterday and it drove like a dream. Loved the power and loved how tame the shifting was in traffic compared to the M5 I test drove a couple of weeks ago. If I do this, I'd be moving from an '06 Acura TL (been very active at AcuraZine.com for the past five years) and I don't want to give up any of my comforts from that car. Couple of specific questions -

1) It looks like it has bluetooth phone connectivity. Is it voice controlled? Any compatibility issues (I'm using a Droid2)?

2) Doesn't look like it has an iPod connection. Any good factory or near factory solutions?

3) Can't tell (yet) if this has Sattellite radio; was it standard or an option?

General questions -

1) Thinking about some mods down the line - good ideas on suspension, rotor, etc?

2) Reliability?

3) Any other suggestions/comments/etc.?

Thanks.
